Notes

strike water 4.25gal at 165
1sp calc chloride to strike water
ambient temp 35F, mash temp 154 (read 144 at first) after mash-in
mash temp dropped to 146F over time, bumped back up to 151 when heater kicked in at ~40min, then back to 147 by end of 60min mash
Started heating to mash-out temp of 165 at 60min
Reached 161F by 25min, raised target mash-out temp to 170F to go faster
Only 164 at 37min, but had to move on
Sparge with 2.75gal took 60 minutes (probably waited too long for it to finish)
Captured 5.75gal in boil kettle
Gravity at 1.051 (1.032 @ 154F) - is this right? I think I saw the same pattern last batch. High mash-out gravity but "normal" post boil gravity
Boil complete with 4.5gal at 1.054 (right at 73% brehouse efficiency. Something is wrong with how gravity readings at mash-out are informing brewhouse efficiency)

Next time
try to configure PID for tighter temp range, maybe lower heater duty cycle to limit overshooting?
set mash-out to 170 to get to 165 faster
Should not have pulled 1/2gal out vs prior brewday. Note Volume in and volume out here (7gal -> 4.5gal). Add 1gal?
